The Pinnacle, the 63-storey tower that would have been the tallest in the City of London's central cluster, has finally been abandoned, according to Gwyn Richards, the City’s new head of design. Originally granted planning permission in 2006, the "helter-skelter" design by Kohn Pederson Fox Associates (KPF) was put on hold in 2011 due to financial issues. Now a replacement scheme is in the works which could be revealed in a matter of weeks.

Construction is well underway for KPF's Lotte World Tower in Seoul, however the mysterious appearance of sinkholes in the surrounding area - as reported by CNN - has brought on a slew of safety concerns. Authorities have been unable to determine the cause of the sinkholes which have appeared in a number of locations around Seoul's Songpa District, although they have ruled out sewerage as a possibility.

The Council on Tall Buildings and Urban Habitat (CTBUH) has announced Kohn Pedersen Fox Associates' International Commerce Centre in Hong Kong as the winner of its first ever Performance Award. The new award recognizes the project with the lowest measured environmental impact on the urban realm, as measured using actual data from the completed construction.

The CTBUH explains the need for the prize, saying: "Most awards programs focus on design intent, as opposed to actual performance – often well-intentioned projects are not revisited, and thus not held accountable." KPF's 484-metre tall office tower won the prize based largely on its policy of collecting and sharing performance data.

Kohn Pedersen Fox Associates (KPF) recently broke ground on what will be Indonesia’s first LEED Platinum building. Currently under construction in the heart of Jakarta, the Sequis Centre Tower is designed as a reinterpretation of the city’s typical glass tower. It will feature ample amounts of office space, along with restaurants, health facilities, retail space, and more.

The Petersen Automotive Museum in Los Angeles has announced that it will celebrate its 20th anniversary in 2014 with a redesign of its interior and a complete transformation of its exterior facade to create a "world class museum that will showcase the art, experience, culture and heritage of the automobile." The exterior design by Kohn Pedersen Fox Associates will give the Petersen a truly unique and iconic look that will hopefully attract architecture and car enthusiasts alike.

Southwark planners have recommended an ambitious proposal by international practice Kohn Pedersen Fox (KPF) and engineer Adams Kara Taylor (AKT II) to add 11 floors to an existing 30-story tower in London. The “incredibly complicated” feat, which would be the world’s first of its kind, would extend Richard Seifert’s 1972 King’s Reach Tower on the South Bank by 44 meters, more than a third its original height.

With a strong passion for successfully integrating tall buildings into their surrounding communities, William Pedersen, FAIA, FAAR has played a significant role as founding design partner in transforming Kohn Pedersen Fox Associates (KPF) into an international powerhouse, whose diverse portfolio is executed by over 600 staff members in six global offices.

In honor of his undeniable success, the New York Chapter of the American Institute of Architects announced Pedersen as recipient of the 2013 AIANY Medal of Honor during a ceremony at Cipriani Wall Street in New York City Wednesday.

KPF recently shared with us their latest design for a 530 meter mixed-use tower in Guangzhou’s Zhujiang Xincheng CBD – the CTF Guangzhou – which is currently under construction. Joining an already impressive skyline, the new tower will form an urban triumvirate with its immediate neighbors – the 440 meter International Finance Center and the 600 meter Canton Tower.

Construction of the Lotte World Tower in Seoul, South Korea designed by high-rise architectural firm KPF is well underway. Won via an international design competition, this new tower will rise up to a pinnacle height of 555 meters. Organized around a mixed-use program including retail, office, hotel and an observation deck at the peak, the tower pulls inspiration from historical Korean arts of ceramics, porcelain, and calligraphy. More details after the break.

Soon to be Shenzhen’s tallest tower at 660 meters, the Ping An Finance Center by KPF will anchor the city’s new Central Business District. Positioned at the southwest corner of the intersection of Yi Tian Road and Fu Hua Road in the Futian District, the tower will connect with neighboring properties in addition to Shenzhen Line 1 Gou Wu Gong Yuan metro station. More details after the break.

International architecture firm Kohn Pedersen Fox Associates (KPF) recenlty announced the inaugural exhibition at its new gallery space in central London, a celebration of the work of German artist and architectural photographer Hans‐Georg Esch. Shown in the UK for the first time, the exhibition presents a selection of photographs taken from Esch’s ‘Cities Unknown’ series. More images and information on the exhibition after the break.

The 2011 MIPIM Asia Awards recently announced that Kohn Pedersen Fox Associates (KPF) garnered five awards out of the 29 awarded, the largest number of awards won by a single architectural firm. Recognized for the Inernational Commerce Centre in HongKong, Wheelock Square in Shanghai, the Abu Dhabi International Midfield Complex, the Xintiandi Hotels, and Singapore’s Marina Bay Financial Centre, KPF will receive their prizes at the prestigious Awards Gala Dinner on November 16.

KPF was one of the first US architecture firms to start working in China, and has had a strong presence there for over 20 years, including growing offices in Shanghai and Hong Kong. These five awards serve as an affirmation of KPF’s unmatched experience and leadership in the region.

ArchDaily sat down with Eugen Kohn and Bill Pedersen back in February. The AD interview with KPF can be viewed here.
